class PatchListFormat p whereSource
Showing and reading lists of patches This class allows us to control how
lists of patches are formatted on disk. For legacy reasons V1 patches
have their own special treatment (see ListFormat
). Other patch types
use the default format which just puts them in a sequence without separators
or any prelude/epilogue.
This means that 'FL (FL p)' etc would be ambiguous, so there are no instances for 'FL p' or other list types.
data ListFormat p Source
This type is used to tweak the way that lists of p
are shown for a
given Patch
type p
. It is needed to maintain backwards compatibility
for V1 and V2 patches.

ListFormatV1 | Show lists with a single layer of braces around the outside, except for singletons which have no braces. Read with arbitrary nested braces and parens and flatten them out. |
